NaHCO3+HCI--->NaCI+H2O+CO2

Chemistry
1 answer:
evablogger [386]3 years ago
7 0

Answer:

Explanation:

percent yield is ratio of actual yield or experimental yield divided by theoretical yield multiplied by 100 .

percent yield of 93.4 % means , the actual yield is 93.4 % what was expected from the reaction on the basis of given chemical reaction .

If in the experimental process , some sodium hydrogen carbonate is left unreacted due to absence of reactant HCl which is also required to obtain product , the percent yield will be increased if the required HCl is also provided .

Hence the percent yield will be increased if required HCl is made available .

Indicate whether the pair of structures shown represent stereoisomers, constitutional isomers, different conformations of the sa
aalyn [17]

The structures shown are examples of Constitutional Isomer.

In Chemistry, an isomer refers to a molecule that is similar to another but has differences. These differences can be:

  • A difference in the constitution: The molecules have the same formula but the connectivities between elements or arrangement is different.
  • Arrangement in space: The molecules have the same formula and connectivity, but they look different to do an arrangement in space of a position.

The molecules shown have the same formula because the elements in each pair are the same. However, the way these elements are connected is slightly different because the Br and the CH3 are connected to different carbons.

Based on this, the difference is the connectivity or constitution, and therefore these are constitutional isomers.

According to the following electron structure, how many valence electrons do these fluorine atoms have? F= 1s12s22p5
ddd [48]
The highest sequence for this shell is the number 2, preceding both the s and p in the diagram. This means that the outermost shell is the second level shell. In this shell, there are 7 electrons, 2 in the 2s orbital and 5 in the 2p orbital.

As a side note (not sure if this is a typo), the electron structure for fluorine begins with a 1s2, not a 1s1.
